No light on new RPi Zero

[alpeace89]

Hi,

Just plugged my new zero in and the light doesn't come on. I haven't yet attached anything else but surely would expect a light even just plugging it in to a power supply?

Cheers,

Alex

It definitely should show activity if you insert a micro SD card.

Yeah thats what I thought. The power cable works fine on my Model B and the SD has noobs on it (although I have adapted it slightly). Any suggestions for my next steps?

Cheers,

Alex

Is the NOOBS card a recent NOOBS image? See viewtopic.php?f=28&t=127022

You MUST use NOOBS 1.5 or Jessie 2015-11-21. All earlier versions will NOT boot on a PiZero (without some updates to the firmware/kernel).

Ok thanks I will download the latest Noobs image and try again as the one from my model B could well be over a year old... Even if it fails to boot should I not get a light on PiZero?

Installing the new version of Noobs solved this.

There is no PWR LED on the Zero. The only LED is the ACT one. It does not even blink momentarily when power is applied if there is no micro-SD card present.

True, without a bootable SD-card the only LED on a PI zero will stay off, the PI zero doesn't have a power LED, but without a polyfuse there is little chance power isn't reaching the PI, and at just 160mA even the worst charger should be able to deliver power reliably, so its not as bad as it sounds, after booting the ACT LED doubles as a power LED, as it will be on, except during SD-card activity. there is no power fail circuitry, so the LED might stay on even when power drops below acceptable levels.
